Frias (back) was placed on the 15-day, major league DL on Monday, Dodgers Insider reports.

Frias was optioned to Triple-A last week after coming off the DL, but that option will now be voided, despite the fact that he started Friday's contest for Oklahoma City. He'll head back to the disabled list for at least the next two weeks, meaning he likely won't be back with the Dodgers until September, when rosters expand.

Frias exited his start for Triple-A Oklahoma City Wednesday with a sore back, the LA Daily News reports.

Frias is pretty buried on the depth chart at this point. At best, he appears to be a September callup candidate to help out in long relief.

Frias (back) was activated from the disabled list and optioned to Triple-A Oklahoma City earlier this week, Bill Plunkett of the Orange County Register reports.

Frias was thought to be making a rehab start with Oklahoma City on Wednesday, but it turns out the Dodgers quietly activated him from the disabled list following Sunday's game, and he is part of the Triple-A roster for now. He could be an option for the big league club later this season, but the Dodgers' rotation is far deeper than it was prior to the trade deadline, so his next big league appearance may come out of the bullpen.

Frias (back) will make his next rehab appearance with Triple-A Oklahoma City, Bill Plunkett of the Orange County Register reports.

Frias may only need one more outing in the minors before he's deemed ready to join the Dodgers, but after the team added Alex Wood and Mat Latos to the rotation at the trade deadline, a starting spot will no longer be available. Instead, look for Frias to occupy a long-relief role for the Dodgers when activated, if he isn't sent back to Triple-A to serve as a starter for Oklahoma City.

Frias (back) will make another rehab appearance with High-A Rancho Cucamonga on Friday, Eric Stephen of SB Nation reports.

The right-hander couldn't make it out of the first inning in his first start with Rancho Cucamonga on Sunday, as he gave up two runs on three hits while recording two outs on 24 pitches (15 strikes). Frias will make another appearance Friday, and if the Dodgers are intent on getting Frias back stretched out for starting pitching depth, he will likely need a couple additional rehab starts.

Frias (back) will begin a rehab assignment with High-A Rancho Cucamonga on Sunday, Dylan Hernandez of the Los Angeles Times reports.

He showed no lingering effects from the back injury in a bullpen session earlier in the week, dialing his fastball up to 96 mph, and has now received the green light to begin pitching in minor league games. It was not made explicitly clear whether Frias will start or pitch out of the bullpen Sunday in his first rehab appearance.

Frias (back) completed a bullpen session Monday, Dylan Hernandez of the Los Angeles Times reports.

No issues were reported and Frias reportedly dialed his fastball up to 96 mph. However, the team has reportedly ruled him out as an option to start Saturday in place of Brandon Beachy, who was optioned to Triple-A Oklahoma City on Tuesday. It's uncertain if or when Frias will return to the Dodgers' rotation.

Frias (back) expects to return to the rotation shortly after the All-Star break, MLB.com's Ken Gurnick reports.

Frias was placed on the 15-day DL Sunday, but the back soreness that landed him there isn't expected to have long-term consequences. He had experienced this issue during his previous three starts, and with the All-Star break around the corner, it was finally time to deal with it. After a bit of extra rest, he'll make one rehab start before reclaiming his back-end rotation spot.

Frias (back) was placed on the 15-day DL Sunday, MLB.com's Ken Gurnick reports.

Frias was originally scheduled to start Monday against the Phillies, but the team will now have to turn to a backup plan. Even though an MRI on his lower back came back negative, his status for that start had rightfully been up in the air. No official replacement has been announced yet, but long relief man Juan Nicasio could be one option.

Los Angeles Dodgers pitcher Carlos Frias expects to return from his back injury shortly after the All-Star break, according to the team's official website.

Los Angeles Dodgers pitcher Carlos Frias expects to return from his back injury shortly after the All-Star break, according to the team's official website. Frias was placed on the 15-day disabled list Sunday due to soreness in his back, after pitching through the ailment during his last three starts. The issue is not expected to require a long-term absence, and Frias hopes he will only miss two starts. He will rest for the next few days, with the plan eventually calling for a lone rehab start in the minor leagues. The Dodgers have yet to announce a replacement starter for Monday's game against the Philadelphia Phillies and Saturday's game against the Milwaukee Brewers. The Dodgers are short on starting pitching depth at the moment, but the team could swing a trade that knocks Frias out of the rotation before he is healthy.

Frias had an MRI taken on his back that came back negative but he's still considered questionable for his start Monday against the Phillies, Bill Plunkett of the Orange County Register reports.

Frias threw a bullpen session Saturday and afterwards his status for Monday's start remained questionable. At this point, he should be considered day-to-day and will likely be a game-time decision against the Phillies.

Frias is expected to make his next scheduled start, manager Don Mattingly told MLB.com's Ken Gurnick on Wednesday.

It appears Frias will keep his spot in the rotation and make his next start Monday at home against Philadelphia, barring a change over the next few days. His ERA has ballooned from 3.86 to 4.39 over his last four starts, although a lot of that is attributable to a six earned run outing against the Giants on June 20.

Frias took a no decision Tuesday against the Diamondbacks as he allowed three runs on seven hits and three walks over five innings.

Frias's WHIP rose to 1.55 and he now has allowed a WHIP of 2.00 or higher in in three of his 12 starts. His 5.2 K/9 ensures the hits will keep coming. He was tagged for his sixth home run Tuesday night and his ERA rose to 4.39.

Frias (5-5) didn't give up a run despite allowing 10 baserunners -- seven hits and three walks -- in five innings during Thursday's 4-0 win over the Cubs. He struck out five.

Frias had previously made four winless starts (with an 0-3 record) in June, and yet he put more men on base Thursday than he did in three of those games. He's also failed to complete six innings in any of his last three starts. Frias represents a low-end starting option entering Tuesday's outing in Arizona.

Frias (4-5) took the loss against the Giants on Saturday, surrendering six runs on five hits and a walk over 5.1 innings.

He's now posted a pair of clunkers in a row, giving up 10 runs in his last 10.2 innings. Frias started out hot, but has had a rough ride lately, as his terrific velocity has not endowed him with much in the way of bat-missing ability. While his somewhat elevated BABIP points to the possibility of some coming moderation in his stats, Frias isn't going to get very far with the 34:19 K:BB he's posted so far this year. He'll get the Cubs at Wrigley on Thursday.

Frias fell to 4-4 after allowing four runs on five hits over 5.1 innings Monday against Texas.

Frias fell into rare trouble with walks, as he walked three batters for only the second time in nine starts. Frias's 5.3 K/9 ranks among the worst among major league starters; if he isn't showing pristine control, he doesn't have much with which to work out of a jam. Frias' ERA sits at 4.14 even though he has allowed just three home runs on the season.

Frias took a no decision despite allowing just one run in 6.2 innings Tuesday against Arizona. He struck out three and walked one.

Frias has three straight quality starts since a disastrous 10-run outing May 24th against San Diego. Frias induced 11 ground balls against Arizona and continues to succeed by keeping the ball down. His ERA is down to 3.86.

Frias (4-3) was charged with five runs -- three earned -- and 10 hits through 6.2 innings Thursday against the Cardinals. He struck out three and walked three in the loss.

After defeating the Cardinals in St. Louis in his last start, Frias was outdone in his rematch with Michael Wacha. With several members of the Dodgers bullpen unavailable after four games in three days in Colorado, Frias stayed in the game longer than usual and exceeded his career high for pitches thrown by 10 with 107 pitches. The 25-year-old will look to lower his workload in his next start Tuesday against Arizona.

Frias (4-2) held the Cardinals to just an unearned run on five hits over seven innings Saturday, striking out three and walking two in a 5-1 win.

A nice bounce-back for Frias after a 10-run disaster against the Padres his last time out, but it's still disturbing that he's only fanned six batters (and walked just as many) in 17 innings over his last three starts. Frias has opened his run in the Dodgers' rotation with generally strong work other than that one forgettable outing, but fantasy owners shouldn't have high expectations for the 25-year-old.

Frias was pulverized during his start against the Padres on Sunday, allowing ten runs on 12 hits and two walks in just four innings.

The 24-year-old had been solid up to this point, and it was far and away his worst outing of the season as his ERA more than doubled to 5.34 after the drubbing. Frias will try and rebound from this forgettable performance on Saturday against the Cardinals.
